TREE-PROTECTOR.

To all iii/2.0m it may concern.

15s it known that I, CARL Hneo SANDAHL, a citizen of the Jnited States,residing at McPherson, in the county of McPherson and State oil Kansas,have invented certain new and useful Improvements in Tree-Protectors, ofwhich the following is a specification.

This invention relates to improvements in tree protectors and its objectis to produce a device of this class comprising a Vll11(ll'lfll metaljacket formed with two or more bulged annular portions which portionsare apertured to admit air and screened to keep out insects and the saidapertured portions are covered with apertured plates removably retainedin place by metal straps passing thereover and secured to the jacket;the purpose of this arrangement being to regulate the amount of airadmitted to the tree; to keep out. excessively cold air from youngtrees, etc. The bulged portions of the jacket permit the same to betitted to a tree having a knotty trunk or a curved trunk and, moreover,to keep a tree in shape that would otherwise be inclined to grow crookedand unsightly; for trees inclined to grow crooked two or more of myprotectors may be placed about the tree one upon the other thus limitingthe amount of curvature of the trunk.

lVith the foregoing and other objects in view the iHYGHtlOl) consists inthe combination and arrangement 01 parts to be hereinafter fullydescribed in the following specification, pointed out in the claims andillustrated in the accompanying drawing which forms a part of saidspecification and in \vhich- Figure 1 is a view of my improved treeprotector applied to a tree. Fig. 2 is a sectional detail showing thelining at the top of my protector, Fig. 3 is a section through one ofthe bulged portions of the device. Fig. 4c is a modification of the topof the device. Fig. 5 is a plan of Fig. 1.

Like reference characters indicate corresponding parts throughout theseveral views.

My tree protector comprises the approximately cylindrical jacket 1formed with annular bulged portions 2. Below the crest in the bulgedportion the metal is apertured as at 3 and the apertured portion coveredby Specification of Letters Patent.

a sliding apertured plate 4 which is retained in position by straps 6secured to the acket. Within the bulged portion of the jacket a screen 7is dis iosed which will admit air to the tree but. keep out insects. Thetop of the jacket is lined with suitable soft lining as at S and thesaid jacket is retained in position upon the tree by adjustable lockingstraps 9 which are each formed with hooks 9 secured by a button 9 to thestrap and adapted for releasable engagement with tongues 9 formedintegral with the straps and disposed at an angle therewith. The tongues9 are formed at varying distances from one end of the strap and the hook9 is carried at the opposite end of the strap so that the strap can beused as a girdle to retain the-jacket 1 upon the trunks of trees ofvarying thicknesses.

The position of the holes in the bulged portion of the jacket is suchthat snow and sleet will not be admitted thcrethrough and in heavystorms some of the plates, on the side of the tree away from the windmay be opened and the others completely or partly closed. The protectoris especially adapted to trees to be tapped as the tree can be tapped inalinement with the openings in the bulged portion of the jacket and thesap withdrawn without exposing the balance of the tree to the inclemencyof the weather. The jacket 1 has its lower extremity embedded in theground and anchored in position by angular supporting legs 10 which aresecured to said jacket by suitable fastening means 11. In Fig. 1 amodification of the acket is shown, the only change in the same being inthe upper end which is serrated as at 12 and. this portion bent backalmost upon the body of the jacket to prevent children or others fromclimbing upon the jacket.

What is claimed is z- 1. As a tree protector, a cylindrical jacketformed with annular bulged portions apertured below the crest of thebulge, sliding apertured plates disposed over the apertured portions ofsaid jacket, supports for said plates and locking straps for saidjacket.

2. As a tree protector, a cylindrical jacket formed with annular bulgedportions apertured below the crest of the bulge, slidable means carriedby said acket and disposed over the apertured portions in the ture inthe presence of two subscribing witbulged portions thereof for openingor closnesses.

in the apertures therein and screens disposed in the apertured portionsof said CARL HUGO SANDAHL' YVitnesses:

5 jacket.

In testimony that I claim the foregoing as my own I have hereto affixedmy signa WM. L. AsPEGREN, E. JERNBERG.
